Provide full SMTP and IMAP account control for delegated mailboxes with attachment-first MIME handling and full-envelope encryption. Use when an agent must read, send, organize, decrypt, and manage mailbox state with strict admin controls.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Mail protocol control

## Purpose

Give an AI agent full operational control of delegated SMTP and IMAP accounts while keeping safety and governance in one place. This skill is built for deterministic tool calls, low token usage, and strict policy enforcement.

## When to use

- User asks for agent-driven mailbox automation over SMTP or IMAP.
- User needs policy-controlled read, write, and destructive mailbox actions.
- User needs token-efficient JSON CLI operations for mail triage and response workflows.
- User needs auditable account actions with confirmation gates for high-impact operations.

## Scope

- In scope: SMTP and IMAP.
- Out of scope for v1: POP3.

## Architecture

- Python domain layer:
  - SMTP via `smtplib`.
  - IMAP via `imaplib`.
- Attachment-first MIME envelope support for send and fetch paths.
- Full-envelope encryption and decryption engine:
  - PSK AES-GCM.
  - Password-derived AES-GCM.
  - Pure-Python OpenPGP.
- Policy gate for all mutating operations.
- One-shot JSON CLI bridge with compact atomic and composite operations.
- Confirmation token lifecycle for threshold-gated destructive operations.

How to install

The exact contents, by fingerprint
mdr add cruxexperts/localsetup/ls-mail-protocol-control@sha256:3faca5efcb1b0393

The line at the top of this page pins the label v1.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
